    Smpdog says: The connection was loose, must have banged it when I was replacing plugs and wires.  How can I reset the engine light w/out pulling the battery? Thanks

    1993 Camry V6... Check Engine Light comes on, but goes out when it rains or is high humidity? Anyone? Anyone? Bueller?

    Hi.

    The Code 24 indicates a problem with the Intake Air Temp Sensor. This device is located in the Air Flow Meter, and is unservicable. You would ned to replace the AFM to cure that. Before I would do that, however, I would unplug/replug the wire connector onto the AFM; it just may be a bad connection; the AFMs rarely fail.



    The Overdrive does not engage until the coolant temperature is 177 degrees. The colder it is, the longer it takes to reach the temp that allows the OD solenoid to engage.



    Please respond if you needs any more assistance.

Disconnect the 15 amp EFI fuse in the fusebox under the hood for 5 minutes. I'd appreciate a FIxYa rating for my assistance. Thanks.

Can a diagnostic connector on 1995 Toyota 4 runner be jumped over with jumper wire to get check engine codes?


There is probably a way to access codes by using a jumper and causing the engine checklight or an integral led to flash in groups. I can't say which pin or pins need jumping.

I suggest you ask the question of google and click on the youtube video.

Check engine light on 89 camry


It means there is a detected problem in engine control that has set a fault code.
The easiest way to deal with this is take it to a repair shop/dealership with the proper scanning equipment and they can extract the faulty code and perform the repair.
If you would like to try it yourself, if you can understand the following,m then get the codes and report back.
\Insert a jumper wire or paperclip between ports T1 and E1 in the diagnostic connector located underhood. ONLY those 2 ports.
When inserted with key on, the check engine light should begin flashing. If it does, it is working. If it doesnt, then you have the wrong pins or the system isnt in idle ground/code pulling condition. The throttle must be closed and the idle tracking switch showing CLOSED before the computer will start flashing codes.

If what I have just said makes NO SENSE, then you really should seek the help of an experienced technician. If what I just said gets you weird flashes, count them. when you 1st turn the key on, it will flash a nimber of times, then at some point a pause, then more flashes, then a longer pause and more flashes. The short flashes are to seperate digits, the long flashes are to seperate codes if there are more than 1. So for example --- pause -- long pause ---- pause ---- would be a code 32 (3 pause 2) and a 44 (4 pause 4).

If you can use that info, post results and maybe I can help. If not, having it checked by a professional may be a better choice.

Toyaota Camry 1994 engine won't start, Engine light on


I would check for fuel,(pressure and injector pulse), spark, and compression, before checking any codes. Lack of any of these basics can result in codes, and then you waste alot of time chasing a symptom, instead of the actual problem.If more people followed basic diagnostics, which always come back to these three basics, rather than chasing codes first,they would find no starts much more quickly.

How do I find the problem when the check engine light is on? Auto parts store tell me their macine is for 1996 and later.


You have the On Board Diagnostic 1 system which applied to most vehicles through 1995. In 1996, the OBD 2 system took effect.

So on your Toyota, the way to read out your codes is with the check engine light itself. When you make a connection with a "jumper" wire and turn the ignition key to on (but not start), the check engine light will flash a series of codes. The connection to make is in a small black box under the hood called the "test connector". The box will be labeled "diagnostic" or "diag". The cover flips open and on the inside of the cover there is a chart showing what each test terminal is for. Using a small jumper wire or a paper clip, connect the two terminals TE1 and E1. Now grab paper and pen and sit in the driver's seat and turn the key to on (not start). The check engine light will start flashing the code(s). The two digit code(s) will repeat until you turn off the key.

A sample code of "35" will look like three flashes at about 1 second intervals followed by a 2-3 second pause then 5 flashes at about one second intervals. There will be another 2-3 sec. pause between codes. Write down all the codes. Turn off the key. Remove the jumper wire from the test connector. You can look up the codes on-line or here or a dealer or parts store should be able to tell you the code definition.

I cannot eject the CDs, its making loud noise


Try something, go inside to your computer, look on the CD drive face, I bet you will see a neat little hole. Open up a paper clip and insert the paper clip straight into the hole about 3/4 of an inch. I bet the drive door opens. Now, go see if you can do the same thing with your Toyota. You may find 2 cd's in the same slot as the original problem.

1993 toyota camry turn check engine light off


Open the hood. Locate a small grey box by the firewall, roughly 1.5 x 1.5 inches. It has a cap that will lift up, but it will not come off. Under the cap, located the terminals E1 and Te1. Using a standard paper clip, "jump" E1 and Te1 together. Turn the key on. Obnserve the check engine light; it will flash, pause and flash again. Count the flashes.
Examples: 2 flashes/pause/4 flashes is code "24"
1 flash/pause/5 flashes is code "15"
Get the codes & get that info back to me so that I will be able to assist you with your issue further.
